Glazer reported that the NFL already had started an investigation before Monday night's game. A Chargers equipment man was seen hiding a possible illegal sticky substance and giving to players. A line judge saw it and had it confiscated and sent to the Broncos and the league.

NFL spokesman Greg Aiello told NFL.com and NFL Network that the league still is gathering facts. The Chargers issued the following statement: "We are aware of the inquiry and are cooperating fully with the league."

The Chargers blew a 24-point lead Monday night against the Broncos and lost 35-24.
